The transmission line is mainly composed of wires, ground wires, insulators (string), line golden gear, pole tower and pull wires, foundation and grounding device. Witnesses: conducting current, conveying power. Ring Tower: The total name of the reinforced concrete rod and the tower.
Pull line: The horizontal load and wire tension of the balancing rod tower reduce the curved moment of the root of the tower.
Insulator (string): It is used to support or suspend wires and ground wires to ensure that there is no flashing between the wires and the tower, and the insulation between the ground wire and the tower.
Circuit gold gear: The total name of the metal parts used in the transmission line (except the tower bolt).
Basic: supporting rod tower, loaded by the rod tower to the earth.
The ground wire is also known as lightning protection: preventing lightning from direct strikes, and at the same time, it has a diversion effect when a lightning strike tower.
Grounding device: Direct thunder currents enter the ground to ensure that the line has a certain level of lightning resistance.
